      final EditText et3=(EditText)findViewById(R.id.editText3);

      {
          bq.setOnClickListener(new View.OnClickListener() {

              @Override
              public void onClick(View v) {
                  // TODO Auto-generated method stub
                  et3.setText(et3.getText()+"q");
                  final EditText et2=(EditText)findViewById(R.id.editText2);
